11 1 CHAPTER 1 Product Overview Features and Benefits The Avocent AMX Switch Series allows multiple users within the switching system to access and operate PC, USB or Sun servers and serial devices at the same time. A basic AMX switching system configuration connects users and servers to one or more AMX KVM (keyboard, video and mouse) switches, as well as other KVM switches (Avocent or non-avocent branded). Any user in the system can access any attached server or serial device by simply switching to it through an AMX switch. An AMX switching system may consist of one or more rack mountable AMX switches and other cascaded KVM switches. The Avocent matrix user station and the Avocent matrix intelligent (AMIQ) module(s). The AMX switch is equipped with the Avocent patented OSCAR graphical user interface, allowing you to use your keyboard or mouse to select any attached server or serial device. Also supplied with each AMX switch is the AMWorks Java -based system administration tool used to manage naming and access information for attached users and servers. Multiplatform The AMX Series switching products feature multiplatform capabilities, enabling your switching system to simultaneously support any combination of PC, USB or Sun servers and serial devices. The AMX switch permits easy access across platforms with a Pinnacle FAK (Pinnacle Fast Action Keyboard), PS/2 or Sun keyboard and mouse. Operated through the AMX switching system, a PC keyboard and mouse can operate a Sun server as easily as a Sun keyboard and mouse can operate an attached PC. Advanced video compensation The AMX user station provides advanced video compensation that maximizes video quality to support long distance communications. The video compensation feature automatically compensates for any losses in video signal to the user station. Multiuser The AMX Series switch allows matrix switching, enabling multiple users to have simultaneous access to different servers and serial devices in the system. For example, an AMX switching system
12 2 AMX Switch Series Installer/User Guide with four users accessing four different servers is a 4 x 4 matrix. Eight users accessing 10 different servers would be an 8 x 10 matrix. Sharing If two or more users need access to the same server or serial device, they can share access through the AMX Series switch. Sharing enables multiple users to switch to the same server at the same time. All connected users can see the server s video, but only one user can enter data at any given moment. LDAP user authentication The AMX Series switch supports the (Lightweight Directory Access Protocol) LDAP user authentication mode. LDAP provides the Active Directory for username and password authentication. Refer to the AMWorks software online Help program on your installation CD for instructions on configuring LDAP on your AMX switch. SNMP interface The AMX Series switch supports the Simple Network Management Protocol (SNMP) to remotely monitor the switch via the ethernet port. Once configured, the SNMP enables network performance monitoring and provides attachment and connection information on servers and user stations in the AMX switching system. Extended keyboard support The AMX switching system supports the Pinnacle FAK keyboard for the AMX5120 and above user stations. The firmware of the AMIQ-PS/2 module used in your system must be compatible with the Pinnacle FAK keyboard to ensure keyboard operability. Broadcast NVision Router control The AMX switching system offers the capability to act as a control plane for specialized broadcast and media industry video and audio routers through the AMWorks software. Both standalone and backup routers can be connected to the AMX switching system to support router redundancy. Refer to the AMWorks software online Help program on your installation CD for instructions on configuring the NVision Router. Seamless cascading The AMX switching system enables users to connect to servers attached to Avocent switches cascaded below the AMX switch through its local port. Table 1.1 lists both Avocent and non- Avocent KVM switches that can be seamlessly cascaded in an AMX switching system. Seamless cascading enables you to connect Avocent KVM switches from a single user interface On-Screen Display (OSD) by configuring an AMIQ module as a Multiple Device Mode (MDM) AMIQ module. Non-Avocent KVM switches can be cascaded in an AMX switching system, but must be activated through the particular switch OSD to continue the operation.
13 Chapter 1: Product Overview 3 See Chapter 4 in this user guide or the AMWorks software online Help program on your installation CD for instructions on managing devices in your AMX switching system.

If your total number of servers is greater than 32 (supported by the AMX5000 switch) or 64 (supported by the AMX5010 switch), you can connect multiple AMX switches together to give dozens of users control of hundreds of servers from one set of peripherals. For additional flexibility, you can attach other Avocent KVM switches to the AMX switching system as well. Refer to Chapter 2 for additional information on tiering an AMX switching system. OSCAR graphical user interface Using the OSCAR graphical user interface, you can select any attached system computer through your keyboard or mouse. The OSCAR interface supports multilevel security with password protection, enabling you to control how much access users have to each server in your data center. For additional security, the OSCAR interface can be configured to log out after a userdefined period of inactivity. When the time-out is reached, the current channel is deselected and the screen goes blank. Users must log in again to access system servers. AMWorks software The AMWorks Java-based system administration software tool supplied with each AMX switch is used to assign names to attached servers and administer naming and access information for attached users. You can also use the AMWorks software to configure AMX switching system installations remotely, eliminating the need to configure each unit separately. The AMWorks software also enables you to monitor and report on all system and switching events and activities.
14 4 AMX Switch Series Installer/User Guide Component Overview An AMX switching system may consist of four main components: One or more AMX switches and other KVM switches Avocent matrix user station Avocent matrix intelligent module [AMIQ module, AMIQ-SRL (serial) module] Unshielded Twisted Pairs (UTP) cables The quantity and type of components you receive depend on the specific configuration you order. The AMX switch The AMX switch provides the framework for the AMX switching system. The AMX5000 switch allows eight users to connect to up to 32 computers and occupies only 1U of rack space. The AMX5010 switch allows 16 users to connect to up to 64 computers and occupies 2U of rack space. Both units can be cascaded to connect larger system configurations. Both units store a full database of user rights and computer names and communicate with the AMWorks software via an IP (Internet Protocol) port. AMX5000 Switch AMX5010 Switch Figure 1.1: AMX5000/5010 Switch Model Comparison The AMX user station The AMX user station (AMX5100 user station, AMX5110 user station or AMX5120 user station) is the interface between the AMX switch and system users. It provides the OSCAR interface for server selection and administration, as well as full compensation for video degradation. The AMX user station is housed in a desktop mounting unit that may also act as a monitor stand.
15 Chapter 1: Product Overview 5 The AMX5100 user station provides one RJ-45 port, enabling the connection of one AMX switch. The AMX5110 and AMX5120 user stations provide two RJ-45 ports, enabling the connection of one AMX switch and one AMIQ module or two AMIQ modules. Connections to two separate switches are not supported on the AMX5110 or the AMX5120 user station. The AMX5120 user station provides skew compensation that maximizes video quality. AMX5010 Switch 64 Servers UTP Cables AMIQ Module AMX5110 User Station 16 Users Figure 1.2: Typical AMX Switching System Configuration The AMX intelligent module The AMIQ module provides the primary interface between an attached device (KVM switch or PS/2, Sun or USB server) and the AMX switching system. It provides all Keep Alive, keyboard emulation, DDC (Digital Data Channel) and AMX switching system support in a server-powered convenient module format. The AMIQ-SRL module is a DCE (Data Communication Equipment) device that provides the primary interface between a serial device and the AMX switching system. It supports VT100 terminal emulation, break suppression and port history in a convenient module format. For information on using the AMIQ-SRL module, refer to Appendix B. These modules eliminate the need for extra rack spaces or additional cables. For ease of installation, each AMIQ module has a factory-assigned unique number that identifies the attached
16 6 AMX Switch Series Installer/User Guide UTP cables server within the system. The connection between the AMX switching system and these modules is through industry standard UTP cabling. The AMX switching system uses video technologies that compensate for the losses that occur in all UTP cables. These technologies make the AMX switch compatible with most UTP cable types and support AMX switch use in environments where there are combinations of UTP cable types and patch panels. The AMX switch will function correctly with any combination of CAT 5, CAT 5e and CAT 6 cables. NOTE: Throughout this manual, the generic term UTP refers to any CAT cable used by the AMX switching system. Safety Precautions To avoid potential video and/or keyboard problems when using Avocent products: If the building has 3-phase AC power, ensure that the server and monitor are on the same phase. For best results, they should be on the same circuit. To avoid potentially fatal shock hazard and possible damage to equipment, please observe the following precautions: Do not use a 2-wire extension cord in any Avocent product configuration. Test AC outlets at the server and monitor for proper polarity and grounding. Use only with grounded outlets at both the server and monitor. When using a backup Uninterruptible Power Supply (UPS), power the server, the monitor and the AMX switch off the supply. NOTE: The AC inlet is the main disconnect. DC installation safety considerations As a safety precaution, install this product in an area with limited or controlled access. A readily accessible disconnect device that is suitably approved and rated shall be incorporated in the field wiring. Connect field wiring from earth ground to the screw terminal marked with the ground symbol. Terminals will accommodate wiring from 26 to 12 AWG (up to 2.5 mm 2 maximum cross section). Strip each wire, insert it in the square opening in the terminal block and tighten the screw above it to a maximum of 70 ounce-inches (0.5 Nm) using either a flat or Phillips-head screwdriver. Rack mount safety considerations Elevated Ambient Temperature: If installed in a closed rack assembly, the operation temperature of the rack environment may be greater than room ambient. Use care not to exceed the rated maximum ambient temperature of the unit. Reduced Air Flow: Installation of the equipment in a rack should be such that the amount of airflow required for safe operation of the equipment is not compromised.
17 Chapter 1: Product Overview 7 Mechanical Loading: Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading. Circuit Overloading: Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of circuits might have on overcurrent protection and supply wiring. Consider equipment nameplate ratings for maximum current. Reliable Earthing: Reliable earthing of rack mounted equipment should be maintained. Pay particular attention to supply connections other than direct connections to the branch circuit (for example, use of power strips).
